MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 778,843, dated January 3, 1905.

Application filed August 3, 1904. Serial No. 219,349.

Beit known that I, HENRYBRAMMER, a citizen of the United States, and aresident of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a full, clear, and exact description.

My invention relates to a mechanical movement for converting a continuous rotary movement into a rotary reciprocal movement; and the object of my invention is to arrange the axis of the continuously-revo]ving actuating device parallel to that of the rotary reciprocal devices. This I accomplish by the means hereinafter fully described, and as particularly pointed out in the annexed claims.

In the drawings, Figure 1 is a plan view of my invention. Fig. 2 is a longitudinal vertical section taken on line 2 2, Fig. l, looking in the direction indicated by the arrows. Fig. 3 is a plan view of my improvements with the dome-gear removed and aportion of the driveshaft, together with the drive-wheel, broken away. Fig. 4 is a similar view showing a portion of the framework in which the dome-gear is journaled broken away. Fig. 5 is a vertical transverse section taken on dotted line 5 5, Fig. 2, looking in the direction indicated by the arrows.

Referring to the drawings, A represents a suitable platform upon which the metal frame supporting the operative parts of my invention are secured. This supporting-frame comprises an elevated bearing a for the continuously-revolving drive-shaft B, which is provided with a vsuitable fly-wheel at one end and with a slightly-beveled pinion C at the other end thereof. The horizontal basal portion of the framework extending in a longitudinal direction from the base of the supporting-walls of bearings a is of a more or less open-work structure having two diverging branches that terminate in the transverse plane of the rotary-reciprocal shaft, (which will be hereinafter more fully described,) and has a vertical yoke a, secured thereto, that has top and bottom cross-pieces in which bearings are provided for the spindles of the dome-gear and the pinions for transmitting the motion of the latter to the former.

The dome-gear E is of a hat-shaped con-A struction having an outwardly-flanged circumferential rim c, the upper side of which is provided with a beveled gear (l, and thc under side of which is provided with a droprim e, which is concentric to the axis of gear E, except at two diametrically opposite points, where it is provided with inwardly-curved cam portions f, substantially as shown in Fig. 4 of the drawings. l Between these cam-surfacesfl the inner circumference of the dome -gear is next its lower edge provided with a series of equidistant inwardly projecting semicircular bosses g g g, which engage and intermesh with, first, a suitably-constructed pinion F on a vertical spindle G, whose ends are journaled in the top or rear plate of yoke a,

and in the bottom plate thereof, and then with a corresponding pinion H on the vertical rotary reciprocal shaft I, whose upper end is journaled in the head-plate of yoke a' and in bearings extending down from the bottom plate of said yoke through thev platform A, substantially as shown in Fig. 2 of the drawings. At a suitable point near their upper ends the spindle G and the shaft I are provided with intermeshing gears J and K, respectively. These gears .I and I( correspond with the pinions F and H, with which they are preferably cast in one piece, but are arranged so that their cogs are stepped or alternated with those of the said pinions F and H.

When the bosses g pass out of engagement with the pinion F, the cam-surface f of the drop-rim e cornes into engagement with a longitudinally-reciprocal stop-block L, which latter comprises a substantially rectangular block of metal, having a longitudinal tenon t projecting down from its under side that moves in a suitable longitudinal guideway t, and is provided witha concavity fr' at its end into which when its moves longitudinally toward pinion F one of the cogs of the latter enter, and is thereby temporarily stopped, so as to prevent further rotation of the spindle G and shaft I. The drop-rim f' extends down into a transverse recess j, which is narrowest at its center of length and widens out toward its ends. The width of the narrow central portion of this recess y' is slightly greater than that of the width of the drop-rim e, so that when the cam-surface f of the said drop-rim passes through said recess it moves the block L toward the pinion F to stop the same and then,

moves its back to its normal position, as shown in Fig. 3 of the drawings. About the time the blockL moves out of engagement with the pinion F the bosses g of the dome-gear which have just passed out of engagement with pinion comes into engagement with the cogs of the pinion H on the rotary reciprocal shaft I. Whenthe said bosses g pass out of engagement with the pinion H, the cam-surface j, preceding the same, will engage the block L and cause it to stop the movement of the gear and then move out of engagement therewith and away fromA the same to permit of the free engagement of the approaching bosses g to reverse the rotation thereof.

From the foregoing it will be abserved that the continuously revolving motion of the dome -gear, which it acquires through the medium of the drive-shaft B and pinion C, by engaging the pinion F (which is gearedto the shaft 1) causes the said shaft I to revolve in one direction and then by the engagement of said bosses g with the pinion H causes said shaft I to revolve vin the opposite direction. Thus each cycle of movement of the dome-gear causes said shaft I to move first in one direction and then in the other to an extent (as will be observed by reference to the drawings) approximately three-fifths of a circle in each direction.

I do not desire to be confined to the exact construction of the various elements of my invention, as hereinbefore described, for while it is preferred to use them the gears J and K might be dispensed with, as likewise the stopblock L. The use of the latter, however, or its equivalent is deemed advisable in order to insure the proper engagement of the bosses g or their equivalents with the cogs of the pinions F and H. -All such modifications as well as changes in the construction of my invention, as hereinbefore described, that do not effect a departure from the principle of operation of my invention I desire'to be considered as contemplating within the scope of the same.
